Letters PatentNo. 91,942, dated June 29, 1869.

APPARATUS FOR I OPERATING CHURNS.

The Schedule referred to in these Letters Patent and making part of thesame..

To all rwhom 'it may conce/rn:

-Be it known that we.l HENRY J. KLINGENBERG,

and JOHN J. MAU, of Davenport, iu the county of Scott, and State ofIowa, have' invented a new and useful Improvement in Spring-Power forGhurns; and we do hereby declare that the following is a full and exactdescription ofthe same, reference. being had to the accompanyingdl'a\\'ing`s,'and to the letters of reference marked thereon.

This invention relates to an improved spring-device for impartingmotion; and consists of certain details of construction, which will morefully appear hereinafter.

In the drawingsr Figure'l is a'perspectivewi'ewof our invention."

Figure 2 is a perspective viewV of the spring.

Figures 3 and 4 are views of parts detached.

To enable others'skilled in the art to make and use our invention, wewill now proceed to describe fully its construction and operation.

A represents the frame-work of our invention, in. .which the-mechanismis located.

a represents the spring, which is of the ordinary -coiled form, one' endof which is attachedto the cross- -bar a.

The spring a is enclosed between the metal disks B, which are providedwith ears, b, by meansof which they are secured in position.

b represents the driving-shaft, upon which the spring a bears, and whichisprovided with the ratchet b".

A cog-wheel, C, is attached loosely to the shaft b, besides theratchet'b", and is provided with a springpawl, which engages the latter.

The cog-wheel C meshes with a pinion` c, on the shait c', which isfurther provided with a bevel-gear wheel, D.

d represents a casing, surrounding theshaft c', between the wheel D andthe frame, on which is a hollow projection, d', which forms the upperbearing'of vertical shaft E, on which is the 'bevel-pinion e, whichmeshes with-the wheel'l).

The lower end of thel shaft E passes through the cross-piece of thetrame A, and is attached in any suitable manner 'to the apparatus to bedriven.

On the end of the shaft D, on the outside of the frame A, is theescapement F, which is of the usual form, andis provided with thependulum f.

' The shaft b also projects beyond the frame A, and

has a square head, to which is tted the key, or crank H.

I represents the brake', which consists of' a strip of metal, passingthrough the frame A, and gradually widening until it reaches the shaftE, where it is bent into a semicircle, and partially clasps anenlargement of said shaft below the pinion e.

On the outside of the frame A, the strip I is provided witlia-screw-thread and thumb-screw, by means of which the brake isregulated.

The operation of our invention will bc readily understood.

The spring a is wound up, by turning the crank H in the properdirection, which will cause the ratchet b to revolve backward, the pawlslipping over the teeth thereof, while the cog-wheel C, notAbeingrigidly attached to the shaft, remains stationary until the spring iswound, which will revolve the, shaft in the'opposite direction, causingVthe teeth of the ratchet to engage the pawland revolve the cog-wheel C,which imparts motion to the pinion cand bevel-gear D e, by which means arotary motion is imparted to the shaft E.

The motion of themechanism may be regulated by shortening or lengtheningthe pendulum, which is provided with ascrew-thread for thezpurpose, orby putting on the brake, which is done by--turning up the set-screw,and, if desired, the motion may be entirely stopped bythe latter device.

This invention may be applied to a variety of purposes, and may be soarranged as to give motion to a horizontal or vertical shaft. .Beingeasily regulated, is well adapted to light kinds of work, particularlychurning, which is the chief purpose contemplated.

Having thus fully described our invention,

\Vhat we claim as new, and desire to secure by Letters Patent, is-

The spring a, confined within the metal disks B, shaft b, ratchet b',cog-wheel A, pinion, c, bevelgear I) e, shaft E,.escapement F, and brakeI, when constructed and arranged as described, for the purpose setforth.
